METALLIC WIN DOW SASH.

Application am mien 7, 1925. Serial mi. 1am.

' To all whomz'tmay concern:

Be it known that 1, CHARLES G. NELsoN, a citizen of the United States, and a resident of Chicago Hei hts, in the county of Cook and State of I inois, have made an invention pertaining to a Metallic Window Sash, which invention is fully set forth in the following specification.

My invention relates to metallic window sashes and more particularly to means for preventing the tilting of an outside sash member.

The purpose of my invention s to improve the construction of the sash so that the various parts will maintain their proper positions. The nature and operation oi my invention will more fully appear as the de- 'scription proceeds.

In the accompanymg drawings forming a part of this specification, Figure 1 is an elevation of a plate which I have added to the sash construction; Figs. 2 and 3 are sections of sash members showing this plate in use in combination with different forms of sashes.

The plate shown in Figure 1 comprises a sheet metal member originally of substantially rectangular shape, but having one, end

10 somewhat narrower than the other end 11. An opening 12 is formed in the larger end of the plate. An offset 13 is formed midway in the length of the plate and flanges Hare bent upward and downward on each side of the plate, so as to stifien it and prevent transverse bending.

In Fig. 2 I have shown a member 15 interposed between an upper and lower window. Theupper window has an inner sashsupporting member 16. A cover plate 17 rests upon the member 15. A metallic plate 18 is positioned against the front of supporting member 16 and isprovided with an outward flange 19. A member 20 is positioned hetween'the flange 19 and the main body of plate 18. At the lower portion of support 16 the plate 18 is bent outward at 21 to receive the upturned flange 22 of cover plate 17, and the outer end of plate 18 is "then. bent outward so that it rests upon plate 17. Member 20 comprises a flange 24 that rests against the vertical portion of plate 18 and terminates in an outwardly turned flange 25. A securing member 26 passes through flange 24 and the vertical portion of plate 18 and secures them in position against supporting member 16.

The glass plate 27 is held in place against flange 19 by an outer sash member 28, which has a flange 29 contacting the outer surface of the glass and a lower flange 30 resting upon flange 23 of the back plate 18. Sash member 28 is drawn against the glass by means of a screw 31 which passes therethrough and through suitable openings in members 24 and 18 into the supporting member 16. I

The draw-plate, which constitutes the es sential element of my invention, is attached to flange 30 of outer sash member 28 by a portion 32 of flange 30- projectingthrough opening 12 and spread above the opening so as to rivet the plates together. The ofiset 13 is located at the end of flange 30 so that the narrower end of the draw-plate rests upon flange 23. Flanges 14 of the drawplate fit snugly beneath flange 25 at the lower edge of member 20 immediately beneath screw 31. This construction holds end 10 of the draw-plate down against flange 23 and revents the upward tilting of flange 30 w en screw 31 isv driven home.

An inner sash-supporting member 33' is provided for the top of the lower window,

and inner sash member 34 is secured in place against supporting n'iember 33 and ishcld in position by a stiffening member. 35 having a flange 36 fastened by securing member 37 to supporting member 33. Y A glass plate 38,.

is-held against the inner sash member by an outer sash member 39 having aflange40 adapted to contact the/glass and a flange 41 adapted to rest against the lower side of member 15. The outer sash member is held in place by a screw 42 passing through said outer member and through an opening in flange 36 and into supporting member 33. The metal of flange 36 is bent outward in the form of a flange 43 to form an opening for the passage of screw 42 and for a further purpose which will be described.

In this form of sash. the draw-plate is sooured to flange 41 by a portion 44 of the metal of that flan e being spun through 0 ening 12 in the raw-plate. The drawp ate has lts narrow end 10 positioned beneath flange 43, with flanges 14 of the drawplate resting against flange 43, so that the inner end of the draw-plate is held firmly against tilting downward when screw 42 is driven home, and in this manner the outer sash member 32 is prevented from tilting.

In Fi 3 another form of sash construction is siown applied to the top of a window. The upper sash-supporting member 45 has therebeneath an inner supporting member 46. A sheet of glass 47 is held directly against the innner supportig member by an outer sash member 48, which has a flange 49 resting against the sheet of glass and a flange 50 positioned against member 45. The outer sash member is held in place by screw 51 passing through said member and into supporting member 46. The drawplate in this construction is fastened to flange 50 by spinning through opening 12 a portion 52 of the metal of said flange. In this case the inner end of the draw-plate is prevented from tilting downward by being drawn against and biting into the wooden supporting member 46, as indicated at 53.

In each of the structures shown there is an offset portion 54 of the outer sash member adapted to receive outer end 11 of the drawplate and hold it securely in position. Tilting of the outer sash member is prevented because one edge is drawn against the glass plate and the other edge is drawn directly against the end of the draw-plate; but even if the draw-plate should be a trifle short, the outer sash member could not tilt so as to raise its lower flange out of place, because that flange is held securely beneath the stiff draw-plate, which in turn, is held down at both ends.

As will be seen, I have provided a very simple construction of draw-plate which may be used in the various ways shown and in analogous ways to prevent the tilting of the outer sash member when it is drawn into place by the screw.

What I claim is:

1. In a. window sash construction, a sash member having a flange along one edge adapted to contact a sheet of glass and a flange along the other edge perpendicular to the sheet, attaching means adapted to ap- {ly drawin force to said member midway F etween said flange to draw said member towards the plane of the sheet, a draw-plate having one end seated in a groove in said member and attached to the second said flange, and means to prevent the draw-plate from tilting relatively to the plane of the sheet.

2, In a window sash construction, a sash member having a flange along pne edge adapted to contact a sheet of glass and a flange; along the other edge perpendicular to the sheet, attaching means adapted to apply drawing force to said member midway between said flanges to draw said member towards the plane of the sheet, a sheet metal draw-plate having longitudinal stiflening flanges and attached to the second said flange of said member, and means to prevent the draw-plate from tilting relatively to the plane of the sheet of glass.

3. In a window sash construction, a supporting member substantially perpendicular to the plane of the sheet of glass, a sash member having a flange along one edge adapted to contact the face of the sheet of glass and a flange along the other edge adapted to rest on said support, attaching means adapted to apply drawing force to said member midway between said flanges to draw the member towards the plane of the sheet, a draw-plate having one end resting upon and attached tothe second said flange of said member and its other end oil'- set so that it rests against said support, and means to prevent the draw-plate from tilting, relatively to the plane of the sheet.

4. In a window construction, a glass sheet, a supporting member positioned across the plane of the sheet, a supporting member inside of the sheet, an outside sash member outside of the sheet and having one flange resting against the sheet and another flange resting against the first said supporting member, an inside sash member between the sheet and the second said supporting member, a screw passing through said sash members into the second said supporting member, and a. draw plate in position to maintain the flange of the outside sash mem ber in position against the first said supporting member.

5. A construction in accordance with claim 4, wherein the outer end of the draw-plate fiests in a groove in said outside sash mem- 6. A construction in accordance with claim 4, wherein the inner sash member is provided with a flange overlying the inner end of the draw-plate.

7. A construction in accordance with claim 4, wherein the inner sash member is provided with a flange in position to hold down the inner end of the draw-plate and in turn be held down by the sore 8. A construction in accordance with claim 4 wherein an opening for the passa of the screw through the inner sash mem r is formed by bending a portion of the metal of said member into a flange in position to rest upon the inner end of the draw-plate.

9. In a metal sash construction, a drawplate comprising a sheet of metal bent so that its ends extend in opposite directions in parallel planes.

10. In a metal sash construction, a drawplate comprising a sheet of metal having longitudinal stiflening flanges along its edges.

11. In a metal sash construction, a drawplate comprising a substantially rectangular. 15

sheet of metal bent so that its ends extend in opposite directions in parallel planes and that longitudinal stiffening flanges are formed along its edges.

In testimony whereof, I have hereunto signed my name to this specification.

CHARLES NELSON.
